The rim 5 has outwardly extending sides 13, and disposed between the sides 13 of the rim 5, there are a plurality of tubes 14, each tube having cushions 15 which are integral with the tubes 14, the cushions 15 also being triangular in shape in cross section, as shown in Figures 1 and 3 of the drawings. These cushions 15 fill the space betweenthe sides 13 of the rim 5 and serve to hold the tubes 14 in position relatively to the rim 5, which -will therefore prevent unnecessary chaling. The

tubes 14 are preferably manufactured with a heavy rubber inner tube 16, a fabric jacket 17 enclosing the heavy inner tube 16, this fab ric jacket 17 having a limitedela's'ticity to permit some stretch when the tube 14 is inated, and enclosing the fabric jacket 17 there is a rubber cover 18 to preserve the fabric acket against unnecessary' deterioration. The tubes 14 are inflated by the usual means, shown in Figures 1 and 2 of the drawings at 19.`

Disposed around the tubes 14 there is a tread 20 which is preferably constructed with a rubber surface 21 and a fabric base 22, but it will be understood that this tread may be manufactured in any approved manner. Integral with this tread 2O there are inwardly disposed cushions 23 which are preferably J -shaped in cross section and whichengage the tubes 14 so that the pressure from the tubes 14 will serve, not only to hold the tread 2O extended at the points where the tubes engage the .said tread, but'also at all other points so that the tread will be held yieldingly extended from one of its sides to the other. The cushions 23, as well as the cushions 15, will also vserve to exert an even Vresistance to the pressure of the tubes 14 `at rsubstaiitially all points.

As will be seen by referring to Figure 1 of the drawings, the sides 24 of the tread 20 Aare disposed inwardly and terminate in beaded portions 25 which are preferably provided with metal cores 26 to serve as reinforcing members and to hold the sides 24 of the tread 20 in position. Y

l/Vhen assembling the parts of 'my resilient tire, the tubes 14 are inserted within the tread 20, the tubes 14 being 'separated by the cushions 23, after which the collapsed rim 5 is disposed in position relatively to the tubes 14 with the sides 13 of the rim 5 abutting against the outer cushions 15. The rim, which has been collapsed up to this point, is then extended into normal position and the tubes 14 yare inflated to press the tubes and the cushions 15 against the rim 5 and the tubes and the cushions 23 against the tread 20.

A treadwith one outer surface is shown in Figure 1 of the drawings, which will serve the ordinary uses, but where it is desired to obtain a better grip on a sandy or unimproved road the tread may have a concave face or outer surface 27, as shown in Figure 4 of the drawings.

What I claim is:

1. In a resilient tire, a rim having outwardly extending sides, a plurality of separate tubes, each tube having integral cusl1 ions at its sides, the cushions on each tube being free from the cushions on adjacent tubes and which are disposed in the space between the sides of the rim, a tread disposed around the tubes, the-tread having beyond the outer tubes inwardly extending sides spaced at all times from the rim and V-shaped cushions integral with the tread and disposed inwardly-to engage the outer adjacent ysides of the tubes. i

2. In a resilient tire, a rim having outwardly extending sides, a plurality of tubes, each tube havingcushions at its sides which lill the space between the sides of the rim, a treaddisposed around the tubes, cushions on the tread, the cushions being disposed between adjacent tubes for supporting the tubes, the sides of the tread beyond the outer tubes extending inwardly and being nonelastic to assist in supporting the tubes.

3. In a resilient tire, a rim having outwardly extending sides, a plurality of tubes, each tube having integral inner cushions which are 'disposed inthe space between the sides of the rini, the inner cushions on one tube being free from the cushions on adjacent tubes, and a tread disposed around the tubes and having cushions free from the first mentioned cushions and which engage the sides of the tubes. Y

4. In a resilient tire, a rim having outwardly extending sides, aplurality of separate tubes, each tube `having two cushions at its sides which are free from the cushions on adjacent tubesand which are disposed in the space between the sides of the rim, the cushions serving to support the 'tubes respectively, a tread disposed 'around the tubes, the 'tread having beyond the outer tubes inwardly extending sides, and .v-shaped cushions extending inwardl from the tread for engaging the outer ac jacent sides of the tubes.

`5.111 'a resilient tire, a rim having outwardly extending sides, a plurality of separate tubes, each tube having two cushions, one at each `side, the cushions 'oneach tube being free from the cushions on adjacent tubes and which are disposed in the space between the sides of the rim, the. cushions serving to support 'the tubes.respectively,'and a tread disposed around thetubes.

6. In a resilient tire, a rim having outwardly extending sidesa pluralityof separate tubes normally disposed on the rim, each tube having integral cushions which are free from the cushions on `the other tubes tomake each tube with its cushions a complete unit, the cushions filling the `space between the sides of the rim, and a tread disposed around the tubes and having integral cushions free from the iirst mentioned cushions and the tubes, the last mentioned cushions being normally disposed between the tubes, the

10 tread and the cushions thereon being moved into operative position bythe iniation ofthe `tubes.` Y i Signed at New York, inthe county of New York, and State `of New York,vthis twenty- 15 second dayof May, 1929."
